the aspect of the meet up you might not understand is that they are trying to promote an idea or a coin and so, they will not talk much about security and the risk that is associated with a lot of the things they are talking about. you are the one that sees it as a meet up, what the organizers likely aim at achieving is get the audience to help them mine a particular project or maybe get them to pay a certain amount that at the end, they will promise to teac them some indebt bitcoin topics that they will not teach them at the end.

real meet-up should be among bitcoin enthusiast who will normally come together to share updated idea about bitcoin and exchange ideas that will aid in the increased adoption of bitcoin as well as things that will help such community of individual stay safe from the dark influence that are in the crypto space. unfortunately, a meet up that is centered at promoting what falls under the category of Ponzi scheme will not offer such kind of platform that will expose participant to the right knowledge.
